OpenEdge GUI for .NET

User Interface is based on .NET forms and controls Windows Forms (WinForms) is the graphical user

interface API included as part of Microsoft's .NET Framework providing event-driven applications

.NET Controls are reusable classes that interact with users and are contained within a form

– Microsoft® .NET Windows Form controls– Ultra Controls for .NET (Infragistics® WinForms)– 3rd-party .NET controls

Development is done entirely in the ABL environment .NET forms can be mixed with ABL windows in the same

application

OpenEdge GUI Client Products Use object-oriented ABL to access .NET objects Data binding between ABL data sources and .NET

controls Write ABL event handlers for .NET controls

OpenEdge Architect Build forms using new Visual Designer – WYSIWYG

editor Basic set of .NET UI controls

OpenEdge Ultra Controls for .NET (optional) Available as an optional product providing additional

feature rich .NET controls from Infragistics

Leverages ABL Single language – No need to learn C#, VB.NET Direct `access to .NET controls – no control container required Data binding between ABL data sources and UI controls Event binding between ABL methods and UI events

Single tool set: OpenEdge Architect No need to purchase, learn or use non-OpenEdge products

Integrates with existing GUI

Independent of deployment topology (client server or n-tier)

Extensible with 3rd party and custom controls

Takes advantage of .NET WinForms technology and advancement

15

Bind ABL data to .NET controls (data binding) New Progress.Data.BindingSource

– Enables design-time binding to business objects – Provides layer of abstraction between data and UI

Can bind UI control with various data sources: – Buffers, queries, ProDataSets

Can bind UI control with various data sources: – Buffers, queries, ProDataSets

ABL data sources tied directly to .NET controls

Summary - ABL to .NET in a Nutshell

Modern, competitive UI in ABL Uses .NET objects Many 3rd party controls available

Visual Designer – WYSIWYG tool Leverages ABL

Object-oriented extensions .NET objects integrated into ABL hierarchy Built-in data type conversions Event-driven programming (WAIT-FOR) Mix-n-match of OpenEdge GUI and OpenEdge GUI for .NET Topology independent: Standalone, C/S, n-tier, web

(WebClient) Developers need only write ABL code
